The panel track solution consists of a rail with permanently attached wide fabric strips; the strips can be adjusted across the rail width using a string mechanism.
It is a special solution for modern interiors, not particularly popular in Poland. Panel track fabric strips can be made from either roller blind fabric or curtain/drapery fabric. Depending on the fabric selection, a varying degree of light can get into the room.
Panel track strips are weight loaded at the bottom with a special slat, which ensures perfect tensioning of the fabric.
Panel track solutions are sometimes referred to as Japanese blinds.
